[1]} undertook the singular spectral analysis (SSA) of the evolution of mean sea-level atmospheric pressure (SLP) since 1850. In addition to dominant trends, a eleven quasi-periodic components were identified, with (pseudo-) periods of \(\sim \) 130, 90, 50, 22, 15, 4, 1.8, 1, 0.5, 0.33, and 0.25 years, corresponding to the Jose, Gleissberg, Hale and Schwabe cycles, to the annual cycle and its first three harmonics. These periods are already known to be characteristic of the space-time evolution of the Earth's rotation axis: the rotation pole (RP) also undergoes periodic motions longer than 1 year, at least up to the Gleissberg \(\sim \) 90 yr cycle [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [1]}. They are encountered in solar physics [14]}, [15]}, [16]}, [17]}, [18]}, [19]}, [20]}, [21]}, [22]}, [23]} and terrestrial climate [24]}, [25]}, [26]}, [27]}, [28]}, [29]}, [30]}, [31]}, [32]}, [33]}.
